損なうという新たな課題が生じていた。<Problems to be Solved by the Invention> By carrying out the method, the invention can be applied to lightweight glass bottles and glass bottles for carbonated drinks, and also a hygiene problem for workers engaged in the treatment process, and various necessary items. Although the problem of high cost that accompanies the installation of the device could be solved with certainty, contact with other objects in the coating process of the glass bottle surface and the distribution process after filling the contents with the glass bottle surface The fine concavities and convexities formed are worn away, and the frost is partially disappeared, becoming transparent and impairing the external appearance.
本発明は、前記のような水系ポリウレタン中のシリカ

る。<Means for Solving the Problems> In the present invention, 5 to 10 parts by weight of a silica-based frosting agent and 0.05 to 0.2 parts by weight of a silane coupling agent are added as essential components to 100 parts by weight of a solid content of an aqueous polyurethane. And a glass bottle coating material, characterized in that the glass bottle coating material is left standing in a vacuum atmosphere for an appropriate period of time.

ミン樹脂等の硬化剤を添加しなければならない。In carrying out the present invention, a curing agent such as an epoxy resin and a melamine resin must be added to 100 parts by weight of the solid content of the water-based polyurethane, in addition to the silica-based frosting agent and the silane coupling agent. .

であればガラス瓶表面がフロストとならず、10重量部を
超えれば被膜の機械的強度が弱くなる。The silica-based frosting agent is hydrous silicic acid,
A bulk specific gravity (JIS K6223) of 0.3 g / ml or less and an average particle size (light transmission type) of 4.5 microns or less are preferable, and the glass bottle surface is frosted if it is less than 5 parts by weight with respect to 100 parts by weight of the solid content of the water-based polyurethane. However, if it exceeds 10 parts by weight, the mechanical strength of the coating becomes weak.

重量部超えれば造膜性を損なう。The silane coupling agent is, for example, one in which a halogen or alkoxyl group is added to one end of a silane molecule and is hydrolyzed to silanol, and the other end is a non-hydrolyzable organic group, that is, a vinyl group or methacryloxypropyl. A group added with a group, aminoalkyl group, epoxy group, chloropropyl group, etc. is used, and if it is less than 0.05 parts by weight relative to 100 parts by weight of the solid content of the water-based polyurethane, the reinforcing effect on the silica-based frosting agent will be insufficient. Enough, 0.2
If it exceeds the weight part, the film forming property is impaired.

Since 2), (3-3), ... Are not completely bonded, they are separated from each other and the secondary aggregates are easily broken, and as a result, the convex portions (5) disappear and become a smooth surface. The frost also disappears. Therefore, 5 to 10 parts by weight of a silica-based frosting agent is added as an essential component to 100 parts by weight of the solid content of the liquid material, that is, water-based polyurethane, and the silane coupling agent is further added to the liquid material in an amount of 0.05 to 0.2 parts by weight. If a liquid material to which a part is also added as an essential component is used as a coating material, the silica-based frosting agent (although not only in the vicinity of the inlet (4-2) due to the action of the reactive group located at the end of the silane molecule ( 3) and the coating (2) are firmly bonded to each other, and the particles (3-1) and (3) constituting the silica-based frosting agent (3).
-2), (3-3), ... become difficult to separate, and the frost formed on the surface of the glass bottle (1) becomes difficult to disappear.

When 0.2 parts by weight of the added granular material is allowed to stand in a vacuum atmosphere for an appropriate period of time, the water-based polyurethane penetrates deeply into the gaps between the silica-based frosting agent, that is, a plurality of granular particles that form the secondary agglomerate, thus When the liquid bottle is used to coat the surface of the glass bottle and cure to form a coating film, as shown in FIG. 3 which is an enlarged view of part A of FIG. 1, granules (3-1),
The depth (4-) of the gap (4) between (3-2), (3-3), ...
The coating (2) permeates and fills 1), and the filling fills each particle (3-1), (3-2), (3-3), ... As a result of the glass bottle (1) being firmly bonded and integrated, the polyurethane coating (2) comes into contact with another object during the coating process or during the distribution process, and that part is abraded and the granules (3) are partially exposed. However, there is no possibility that a part thereof will fall off, the convex portion (5) will not disappear, and therefore the frost will never disappear.
